We're having this problem with our Series 2? single tuner TiVo and our Series2? dual tuner TiVo, but not on our Premiere. On all of them our season passes are being recorded correctly. On the two SD units only - but on both of them - TiVo suggestions may or may not be the programs they say they are (about a 50-50 chance). The channels it says it recorded, but did not, are correctly shown as in the channel list as channels we do receive. On one of the TiVos EVERY time it records the wrong channel the channel it actually records is the local CBS station. This is happening on the dual tuner. I know of no way to determine which tuner recorded which show, so I don't know if this affects only one of the tuners (the reason for the 50% chance of being correct)??

This problem surfaced with both TiVo units at the same time (a few weeks ago). Both are connected to cable boxes, with IR channel-changing. Those connections appear to be fine. I've rebooted both of the TiVos and both of the cable boxes, with no improvement.

bshrock: no - they are channels we DO receive
lpwcomp: I think you hit on it. When I manually change the channel to any of the channels that were supposed to be recorded the info screen shows that channel and the program on that channel. The program that actually shows does not change, though, and has a CBS logo in the lower right corner.

I'm going to contact my cable provider. Thanks!

You might try changing the settings on the TiVos and see if a different remote code works.

Two different people just happened to have their IR blasters go bad at about the same time?

I would try changing the TiVos' channel changing behavior (Messages & Settings > Settings > Channels > Channel Changing). Try using the "Advanced Setup" and see if it will let you change the number of digits and whether or not it issues an "Enter". Try various combinations. If that doesn't work, repeat guided setup and try different options for cable box remote codes, speed,etc.

It could be that Verizon updated your cable box software (or enable/disabled some feature). Going through the remote code set up again will hopefully help.

When I had Comcast they'd periodically disable the serial input to the box and I'd have to call, elevate to a supervisor etc. to get it re-enabled (simply because I didn't trust the IR blaster all that much) when ever they updated the box.

But the remote code setup doesn't make the remote control the STB. There is a "signal loss" between the Tivo and the STB....right?

I'll swap out the IR with one of the bedroom IRs....see if that makes any difference.

No, it enables the TiVo to control the STB through the IR blasters. Think of the TiVo as a simultaneous translator.

TiVo receives channel change remote code.
TiVo sees that it is configured with a Cable Box.
TiVo gets the remote codes for the cable box.
Tivo sends cable box channel # remote commands over IR blaster to Cable Box.
Cable Box sees commands and changes to selected channel.
Note that when you use the TiVo remote channel up or down, the TiVo sends the numbers of the next or preceding channel based on what channel it thinks it is on.

What I'm thinking is possible is that the cable box was originally programmed to recognize two sets of commands - one used by its remote and a secondary set to be used by other devices and that the secondary set has been disabled.

When you enter numbers on either remote, do they appear on screen prior to the actual change? I'm not talking about either banner, just the actual digits as you enter them.

I googled your STB and one of the things that came up was this wherein it is suggested is made to try using the Scientific Atlanta or, if that doesn't work, the Verizon Motorola STB codes.

If none of this resolves the problem, you might try rerunning guided setup.

Unfortunately, the optimal solution (get new TiVos and CableCARDs) is a bit pricey.

again this is an existing setup that just stopped working...so it is already set for Scientific Atlanta.

I actually have a Tivo Premier still sitting in the box that I bought during that $50 sale....maybe this will be an impetus to set it up. Although, the box with the issue has a Lifetime Sub on it...so it better work if i move it to a bedroom.

After many attempts to figure out why two of our Tivo Series 2 DVRs lost their ability to change channels - tho with different symptoms (see original post) - I went back to basics. I rebooted the cable boxes and the Tivos, then re-ran Guided Setup. The ST unit regained function after the first try. It had to try a bunch of methods of changing channels on the cable box, but it works now. On the DT unit it seemed to be making progress until it changed the channel to ch 1. That's the video on demand channel. It got there, but it would not change from that channel. I went through the whole process again. This time, when it was ready to change from ch 1 I used the cable box remote's channel up button to get off of VOD, then responded to Tivo's asking it I was ready to attempt to change the channel. Voila! Both units are again working properly.
